Southern Pacific Causeway cuts across the northern edge of this remote Box Elder County landscape, marking a vital industrial artery through the Great Salt Lake desert. The terrain is defined by the prominent Hogup Ridge, which terminates at Hogup Point as it descends into the surrounding flats. To the east, the area known as The Threshold indicates a transition in the basin's geography. This 2020 survey documents the modern topographic profile of the ridge, a site significant for its archaeological depth and isolation within the salt flats of northern Utah.
